HY-101897

Fura-2 AM 5+ Cited Publications Fura-2 Acetoxymethyl ester	Fluorescent Dye	Others
Fura-2 AM is a membrane permeable, intracellular, UV light-excitable and ratiometric fluorescent Ca ²⁺ (calcium ion) indicator. Fura-2 AM crosses cell membranes and is converted to Fura-2 (HY-D0110A) via cellular esterases. Fura-2 AM can be used to detect calcium in cells.

HY-D0127

Merocyanin 540	Fluorescent Dye	Others
Merocyanin 540 is a fluorescent membrane probe that selectively stains the membranes of a wide variety of electrically excitable cells, but not those of nonexcitable cells (Ex/Em: 540/580 nm) .

HY-108594

PD-118057	Potassium Channel	Metabolic Disease
PD-118057 is a hERG channel activator without causing hERG blockade. PD-118057 activates hERG channel to suppress changes in membrane excitability .

HY-W013712

GI-530159	Potassium Channel	Neurological Disease
GI-530159 is a selective opener of TREK1 and TREK2 potassium channels. GI-530159 displays selectivity for TREK1/2 over TRAAK, TASK3 and other potassium channels, with an EC₅₀ of 0.76 μM for TREK1. GI-530159 reduces rat dorsal root ganglion neuron excitability and shows potential analgesic effect .

HY-135000

Decarbamoylsaxitoxin DcSTX; DecarbamoylSTX	Endogenous Metabolite Drug Metabolite	Neurological Disease
Decarbamoylsaxitoxin is a sodium channel inhibitor that blocks the influx of sodium ions through the membranes of excitable nerves and skeletal muscle cells, thereby preventing the formation of action potentials. Decarbamoylsaxitoxin is an acidic hydrolysis product of saxitoxin, and its toxic effects on mice are identical to those of saxitoxin. Decarbamoylsaxitoxin inhibits veratridine- and ouabain-induced swelling and lysis of mouse neuroblastoma cells by blocking Na ⁺ channels. Decarbamoylsaxitoxin can be used in studies related to paralytic shellfish poisoning .

HY-P1281

Kaliotoxin	Potassium Channel	Neurological Disease
Kaliotoxin is a peptidyl inhibitor of neuronal BK-Type. Kaliotoxin can specific inhibit Kv channels and calcium-activated potassium channels. Kaliotoxin can be used for the research of the regulation of membrane potential and neuron excitability .

HY-135131

Synthalin hydrochloride	iGluR	Neurological Disease
Synthalin hydrochloride is a K+ channel blocker with neuronal excitability modulating activity. Synthalin hydrochloride has an effect on NMDA-mediated depolarization, possibly through receptor-mediated modulation of L-glutamate and serotonin (5-HT). The use of Synthalin hydrochloride can enhance the understanding of changes in membrane potential of different neurons and help study the role of polyamines in neuronal excitability .

HY-168166

CHET3	Endogenous Metabolite	Neurological Disease
CHET3 is a sex-selective activator with potent analgesic activity. CHET3 was discovered to be a highly selective omnidirectional modulator of TASK-3-containing K2P channels, including TASK-3 homologues and TASK-3/TASK-1 heterologues. CHET3 exhibited significant analgesic effects in multiple acute and chronic pain models in mice, which could be abolished by pharmacological means or genetic knockout of TASK-3. CHET3 is able to functionally modulate the membrane excitability of specific small sensory neurons, which supports its analgesic effects on thermal hypersensitivity and mechanical hyperalgesia in chronic pain .

HY-108594R

PD-118057 (Standard)	Reference Standards Potassium Channel	Metabolic Disease
PD-118057 (Standard) is the analytical standard of PD-118057 (HY-108594). This product is intended for research and analytical applications. PD-118057 is a hERG channel activator without causing hERG blockade. PD-118057 activates hERG channel to suppress changes in membrane excitability .

HY-19185

ZD-6169	Potassium Channel	Endocrinology
ZD-2767 is a selective ATP-sensitive potassium channel agonist. ZD-276 reduces cell membrane excitability and contractility by activating K_ATP channels in bladder smooth muscle. ZD-2767 is promising for research of overactive bladder .

HY-DY1101

Fura-2 AM (solution) Fura-2 Acetoxymethyl ester (solution)	Fluorescent Dye	Others
Fura-2 AM (solution) (Fura-2 Acetoxymethyl ester (solution)) is a membrane permeable, intracellular, UV light-excitable and ratiometric fluorescent Ca ²⁺ (calcium ion) indicator.
